The unique value indicates the discrimination quality of the fiducial in contrast to other structures found in the
vicinity of the fiducial. The display varies between
–
0 = inadequate and
–
100 = very good discrimination.
Experience shows that a unique value should be achieved of at least 60 for fiducials and ink dots.
Fig. 7.5.7
NOTE
Should you nevertheless want to use a fiducial with a low unique value, you should ensure a good quality
value for the fiducial (see Section 7.5.3.5 Option “Test fiducial”).
If in addition the quality too is bad, it is better you select another fiducial (see Criteria for the creation of fidu-
cials in Section 7.2.5).
●

7.5.3.3 Option “Edit fiducial”
NOTE
The menu “Edit fiducial” is only activated if you have already entered a fiducial number and a definition already
exists for the number selected.
Fig. 7.5.8
A description of the menu with its options can be found in Section 7.5.4.
7.5.3.4 Option “Center fiducial”
NOTE
The option “Center fiducial” can only be activated if you have already entered a fiducial number and a defini-
tion already exists for the number selected.
If these conditions are met, the menu “Teach fiducial” disappears and the video image is displayed on the
screen. The figure shows the 2D fiducial structure and the row and column profiles of the 1D structure for
exact determination of the center of the fiducial. In addition the header and footer lines are displayed.
